IMPROVEMENT 1N oilL-cuPs.

Specication forming part of Letters Patent No. 125,405, dated April 9, 1872.

To whom it may concern:

Be it known that I, CHARLES H. PAR- SHALL, ot' Detroit, in the county of Wayne and State of Michigan, have invented anew and useful Improvement in Oil-Cups 5 and I do decla-re that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specication, in which- Figure l is a perspective iew ot' the eXterior of my improved oil-cup, and Fig. 2 is a perspective sectional view of the interior thereof.

The nature of this invention relates to an improved construction of oil-cups for lubricating machinery and for regulating the tlow of the oil from the cup to the journal. The invention consists in combining with the stem and cap as constructed a conducting and clearing wire, as more fully hereinafter set forth.

In the drawing, Ais a tubular metallic stem, formed with a rectangular nut, a. Below this nut the steml is slightly coned, and is threaded part, and over it is slipped a metallic cap, B, closed at the top. In the side of the plain part of' the stem an aperture, c', is made, communicating with the passage or bore of the stem. In the side of the cap is a correspond ing aperture, b, which, when turned to coincide with the aperture in the stem, will allow the oil in the bowl to Ilow through the stem to the journal. By rotating the cap axially on the stein the opening may be partially closed to regulate the flow or to shut it oli' entirely. C is a wire, which is placed in the canal of the ste1n,extending below the mouth thereof, and resting upon the journal to be lubricated, and extending to the top of the canal. The object of this wire is to conduct the oil to the journal and to render its iiow uniform, in which case the slight vibration imparted to it by the moving part or journal makes its operation absolutely certain, and is a sure preventive against the guinming of the oil in the canal.

What I claim as my invention, and desire to secure by Letters Patent, is

In combination with the stem A and cap B, constructed as described, the wire C, as and for the purpose specified.
